You may want to check the ac voltage with a good "true RMS" meter and see what
the results are, some (most) new Freq Drives, and soft start drives may have an
issue with a high RMSJerry

Subject: Re: [RE-wrenches] Inverter/AC pump compatibility question
Allan,
I have several customers running the Grundfos SQE series on their
modified square wave inverters.
To be clear, those most recent was about 5 years ago, so perhaps
there's been a design change since then.

Wrenches,
Has anyone powered a Grundfos SQ or SQE series soft-start AC
submersible pump from a modified square wave inverter?
I need to run a 1/2 hp 115V AC sub on a 1990-era Heart EMS
2800-12. The customer likes his equipment so I'm not encouraging
an inverter upgrade.
Thank you,
Allan
